Chronic pericarditis
myocardium
Left ventricle
Fibrous pericardium
Heart wall
Auricle
Tricuspid valve
Fibrous skeleton
endocardium
epicardium
Pectinate muscle
Acute pericarditis
Right ventricle
Chordae tendineae
Visceral layer
Serous pericardium
Mitral valve
accumulation of pericardial fluid in heart wall that affects heart filling with blood, heart output and cause low blood pressure
thin, delicate double layer around heart with outer parietal and inner visceral layers
Tendons that hold AV valves. They connect to papillary muscles.
Right atrioventricular valve
also called epicardium
made of cardiac muscle
pouches on anterior surface of atrium that increases capacity of atrium to hold more blood
found in inside of right atrium, that extend into auricle
thin layer of endothelium thin layer of endothelium
has 2 layers (thin outside visceral layer of serous pericardium made of mesothelium), inside made of delicate fibroelastic tissue and adipose tissue
4 rings that are fused and support the 4 heart valves and prevent overstretching and separate flow of electrical impulses
tough, non elastic, made of dense irregular connective tissue and anchors heart to mediastinum
has 3 layers epicardium, myocardium and endocardium
Left atrioventricular valve
has a thicker wall, and pumps blood through aorta to all over the body
sometimes caused by viral infection
pumps blood to lungs via the pulmonary artery
